- •
Um Zariq zircons were crystallized at high temperatures relative to Malhaq ones.
- •
Malhaq zircons are from mafic source and Um Zariq zircons imply evolved parent rocks.
- •
Both zircon suites are unaltered magmatic with no hydrothermal or metamorphic effect.
- •
All Um Zariq and most of Malhaq zircons are continental crust zircons.
- •
Peak metamorphic conditions reached at burial depth of 14–16 km.
